Application filed March 10, 1914. Serial No. 823,708.

To all whom t may concern.'

Be it known that I, CHARLES J. ALLEN, a citizen of the United States, residing at San J ose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in 'Cil-Heating Devices, of which the following is a specioation.

My invention relates to an oil heating device, and more particularlv for heating that general. class of oil known as crude petroleum fuel oil which requires the proper amount of heat in order to have the same iiow through the pipes to the burners and there mix and blend with the air and steam as required for a. more perfect combustion.

A further object of my invention is to provide an oil heating device of simple and durable construction capable of being used in connection with the air and steam inlets to a burner without the necessity of disturbing the valvular arrangement of the oil heating device or in any manner altering or changing the construction thereof.

A further object is to provide means whereby the temperature of the oil may be ascertained while the same is feeding through the pipes and one in which the oil may be fed to the burners in the required amount, and one in which the live or direct steam from the boiler may be atomized and mingle with the heated oil as the same enters the burners for a more perfect combustion.

A still further object of the invention isr generally to improve this class of devices so as to increase their utility, durability and efliciency.

Further `objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor detailsof construct-ion may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and accompanying drawing, in which the iigure is a front elevation of my device showing, pipes, valves, andl other pipe fittings in place as constructed. f Y

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference numerals.

The improved oil heating device forming the subject matter of the present invention,

comprises a main iron steam pipe 1 attached to the upper port-ion of boilers 2 2a by controlling valves 3, and three way `l pipe connections 4t. Said main steam pipe 1 isy the direct steam pipe and may be of any size required and turned downward by quarter-turn elbow 5, and connecting with T connection at 6 to which is connected steam pipe 7. Pipe 7 is of the same size as pipe' 1 and is for the purpose ofcarrying the direct steam to burners 8 which ent-er the `iireboX door at 9. T connection shown at 10 connected to pipe 7 in front of boiler 2 shows a smaller steam pipe 11 connected thereto to which is connected valve 12, this controlling valve is for the purpose of governing the amount o-f direct steam to burner 8. Below burner 8 and connected to oil pipe 11a is oil controlling valve 13, this valve is for the p-urpose. of governing the amount of oil fuel feed to burner 8. Betweenboilers 2 and 22L on steam pipe 7 is connected cut-out valve 14, this valve is for the purpose of shut-ting off the direct steam from burner 8 under boiler 2a when the same is not in use. In fro-nt of boiler 2a and connected to steam pipe 7 is T connection 15 to which is connected a smaller steam pipe 16, this pipe having a T connection 17 with a larger steam pipe 18. Below the T connection 17a distance and connected to steam pipe 16 is steam controlling valve 19, this valve is for the purpose of governing the amount of direct steam to burner 8. Below burner 8 and connected to oil pipe 11a is oil controlling valve 20, this valve is for the purpose of governing the amount of oil fuel feed to burner 8. Said steam pipe 18 having a cut-out valve 21 connected thereto which is'for the purpose of shutting 0E the direct steam from passing through steam pipe 18 when the same is not required. Connected to said steam pipe 18 is quarter-turn elbow 22 which turns the steam pipe 18 downward vto which is connected T connection 28 and cut-out valve 24, said valve being connected to main steam' pipe 1 by T connection 25. Valve 211 is for the purpose of shutting ofi the direct steam from passing through pipe 18 to main pipe 1 when the same is not required. Connected to T connection 23 is the extension of steam pipe 18 to which is connected controlling valve 26,

this valve is for the purpose of controlling steam pipe '18"being connected to main steam pipe 1 by quarter turn elbow 27, and T connection 28. Steam controlling valve 29 is here shown on main steam pipe 1, thisk valve is for the purpose of admitting direct, steam to any further connections that may` be made thereto for the same purpose. Contro-lling valve 30 on steam .pipe 7 is also for the purpose of controlling the steam -to any addition to said device that may be required, and controlling valve 31 on main pipe 1 is-also for the same purpose as valves 29 and 30. n

Connected to the upright portion of main steam pipe 1 is controlling valve 32, this valve controls the amount of direct steam required in the lower portion of main pipe 1. At the lower end of said upright portion of main pipe 1 is a four-way connection 33 connected thereto. Connected to the lower por-tion of said connection 33 is a drip valve 34, this valve is fory the purpose of removing any and ally water that may accumulate in that portion of main steam pipe 1 from-the condensation of steam passing therethrough.

Connected to the lower horizontal portion of main st eam pipe 1 is three yway T connection 35, connected thereto in an upright position is a short piece of main steam pipe l connected to said three way T connection 35, to which is connected quarter turn velbow 36, connected to said elbow is cut-out valve 37, lthis valve -is for the purpose of controlling the amount of steam required 'to pass on through steam pipe -1 to three wayT connection 25 where'the same is then controlled by vcontrolling valve 24. Connected to cut lout valve 37 in a horizontal position is a short ,piece of steam pipe 1 to which vis connected quarter-turn elbow 38, to which is connected in an upright position a short piece of main steam pipe 1, the same connecting .with three way T connection 39 which is connected to the lower horizontal portion of main steam .pipe 1,#thus completing fthe connection of main direct steam vpipe 1- in front of boiler 2 to that in front of boiler 2a. 'Connected tothe llower portion of three way connection T 25 is drip valve 40, this valve -is for ythe purpose of removing any and all water that may accumulate in that .portion of mainfsteam pipe 1 romthe condensation `of steam :passing therethrough. Cil pipe 112L enters the klower portion of main steam .pipe 1 at 41, and is carried o'n through said pipe 1 as far as required. A packing lbox is shown `at 42 which `'closely lits around oil pipe 11il and screws into connection 33, `this packing box 42 is for the purpose of preventing any leakage of steam or water around oil pipe 112L at this point.
